DNA is double stranded helix, connected by what could be described as "ladder rungs". These rungs are actually nucleotides, the

building blocks of DNA. A sequence of three of these nucleotides is known as a codon. Codons are important in the composition of proteins, because each codon calls for a specific

Answer:

Codons are important in the composition of proteins, because each codon calls for a specific amino acid.

Explanation:

The genetic message contained in the DNA is formed by an alphabet of four letters that correspond to the four nucleotides: A, T, C and G.

With these four letters it is necessary to form "words" that have the meaning of "amino acids".

The genetic code of DNA is expressed by broken bases, which were called codons. Each codon, formed by three letters, corresponds to a certain amino acid.

The correspondence between the trio of bases of DNA, the trio of bases of RNA and the amino acids specified by them constitutes a message in code that came to be known as "genetic code".

Answer:

A. The bacteria are breaking down sugars in the absence of oxygen.

Explanation:

Bacteria are microscopic single-celled organims. These organisms may produce their own source of chemical energy, or consume and absorb chemical energy made by producers.

They break down chemical energy like glucose through lactic acid fermentation in their cytoplasm, without the presence of oxygen.

In Glycolysis:

2 molecules of ATP are used to break up glucose into 2 molecules of pyruvate, 4 ATP and 2 electron carrying NADH molecules. Since 2 ATP are used, a net 2ATP are produced by this process.

Then, pyruvate is converted to lactic acid, producing 2 NAD+, used as electron carriers.
